1. CARE OF PATIENTS WITH DIABETES MELLITUS JANNA WICKHAM RN MSN LSSC FALL 2013 Chapter 20

2. Types of Diabetes Type I Type II Gestational Other

4. Assessment History Blood tests:  Fasting plasma glucose (FPG)  Oral glucose tolerance test (OGTT)  Other blood tests for diabetes  Screening for diabetes  Ongoing assessment—  glycosylated hemoglobin assays(HbA1c),  glycosylated serum proteins and albumin,  urine tests  tests for renal function-GFR

5. Insulin Physiology

6. Acute Complications of Diabetes Diabetic ketoacidosis Hyperglycemic-hyperosmolar state (HHS) Hypoglycemia from too much insulin or too little glucose

7. Health Promotion and Maintenance Control of diabetes and its complications is a major focus for health promotion activities.

8. Chronic Complications of Diabetes Macrovascular and microvascular disease Retinopathy (vision problems) Nephropathy (kidney dysfunction) Neuropathy (nerve dysfunction)

9. Macrovascular Complications Cardiovascular disease Cerebrovascular disease

10. Microvascular Complications Eye and vision complications Diabetic neuropathy Diabetic nephropathy Male erectile dysfunction

11. Type 2 Diabetes and Metabolic Syndrome Metabolic syndrome, also called syndrome X, is classified as the simultaneous presence of metabolic factors known to increase risk for developing type 2 diabetes and cardiovascular disease.

12. Drug Therapy Oral therapy:  Sulfonylurea agents  Meglitinide analogues  Biguanides  Alpha-glucosidase inhibitors  Thiazolidinediones  Combination agents

13. Insulin Therapy Types of insulin  Rapid  Short  Intermediate  Long Insulin regimens Factors influencing insulin absorption Mixing insulin

14. Potential for Hypoglycemia Blood glucose level <70 mg/dL Diet therapy—carbohydrate replacement Drug therapy—glucagon, 50% dextrose, diazoxide, octreotide Prevention strategies for:  Insulin excess  Deficient food intake  Exercise  Alcohol

15. Complications of Insulin Therapy Lipoatrophy Lipohypertrophy Dawn phenomenon Somogyi’s phenomenon

17. Alternative Methods of Insulin Administration Continuous subcutaneous infusion Injection devices New technology

18. Patient Education Insulin storage Dose preparation Syringes Blood glucose monitoring Signs and symptoms of hypo or hyperglycemia Infection control measures Diet therapy

19. Principles of Nutrition in Diabetes Protein Dietary fat and cholesterol Fiber Sweeteners Alcohol

20. Hyperinsulinemia Chronic high blood insulin levels that can occur with intensive treatment schedules and may result in weight gain. These patients may need to treat hyperglycemia by restricting calories rather than by increasing insulin. Weight gain can be minimized by following the prescribed meal plan, getting regular exercise, and avoiding overtreatment of hypoglycemia.

21. Exercise Therapy Regular exercise is an essential part of a diabetic treatment plan Benefits of exercise Exercise in the presence of long-term complications of diabetes Assessment before initiating an exercise program Guidelines for exercise

22. Surgical Management Transplantation of the pancreas Whole-pancreas transplantation Islet cell transplantation

23. Proper Foot Care Foot injury is the most common complication of diabetes leading to hospitalization Prevention of high-risk conditions Peripheral sensation management Footwear Foot care

25. Hammertoe

26. Testing Sensation

27. Wound Care Wound environment Débridement Elimination of pressure Growth factors

28. Chronic Pain Neuropathic pain results from damage to the nervous system anywhere along the nerve Pharmacologic agents Nonpharmacologic interventions

29. Risk for Injury Related to Disturbed Sensory Perception: Visual Interventions include:  Blood glucose control  Environmental management:  Incandescent lamp  Coding objects  Syringes with magnifiers  Use of adaptive devices

30. Ineffective Tissue Perfusion: Renal Interventions include:  Control of blood glucose levels  Yearly evaluation of kidney function  Control of blood pressure levels  Prompt treatment of UTIs  Avoidance of nephrotoxic drugs  Diet therapy  Fluid and electrolyte management

31. Potential for Diabetic Ketoacidosis Interventions include:  Monitoring for manifestations  Assessment of airway, level of consciousness, hydration status, blood glucose level  Hyperglycemia management  Management of fluid and electrolytes

32. DKA

33. Potential for Diabetic Ketoacidosis  Drug therapy goal—to lower serum glucose slowly  Management of acidosis  Patient education—prevention

35. Potential for Hyperglycemic-Hyperosmolar State (HHS) Hyperosmolar state caused by hyperglycemia Differences of DKA and HHS Monitoring Fluid therapy Continuing therapy

37. Community-Based Care Home care management Health teaching Health care resources
